Accused Colorado shooter has 'rammed into his jail cell wall and jumped off his bed in halfhearted suicide attempts'

James Holmes has allegedly attempted to take his own life multiple times by jumping off his bed and hitting himself against his jail cell wall since he has been incarcerated after the Aurora, Colorado massacre.

Law enforcement sources have said Holmes has made 'halfhearted' suicide attempts while he has been jailed at the Arapahoe Detention Center in Centennial, Colorado and his most recent attempt is the cause for his recent hospitalization on Tuesday.

His attorney would only say Holmes was receiving care for unspecified reasons, which has delayed his scheduled court hearing on Thursday.

Vague: Holmes' attorney Tamara Brady (pictured on July 23 with her client) would not specify the cause of the 24-year-old's hospitalization, saying only 'it's not as simple as a migraine'

Sources told KCNC-TV that Holmes, 24, has made multiple suicide attempts, though none have resulted in serious injury.

He received medical attention for at least of his tries but the insiders called the attempts to end his life 'halfhearted.'
